Probability


Definition.

Probabilities are a branch of mathematics that is dedicated to the study of certain so-called randomized experiments, ie coming from the random, which we know all the possible outcomes, but can’t be sure of what will be the
exact outcome of the experiment.


Description.

The probability is measured by a number between 0 and 1, if an event never occurs its probability is 0, while if the event occurs its probability is 1. Thus, the odds usually come expressed as fractions or percentages.
